Turbochargers are used to increase engine performance without adding a lot of weight to a vehicle. Turbochargers compress air by utilizing the pressure from a vehicle's engine exhaust gases to drive a compressor wheel. This wheel allows air to flow into the engine and improves an engine's horsepower. Turbochargers are often used in race cars and high-performance sports cars, as well as large diesel engines. You can buy a turbocharger, which can be costly, depending on the model. Building your own turbocharger is much less expensive.
Determine the type of turbocharger that will best fit your vehicle by doing some research.
Purchase a turbocharger with the desired power level and operating range, as well as a turbo mounting flange and bracket that suits the turbocharger.
Purchase exhaust tubing that is sized to the turbo exhaust outlet, as well as exhaust tubing that is sized to the turbo compressor outlet.
Mount the turbo to the engine with the mounting flange and bracket. Position the turbocharger as close as possible to the front of the exhaust manifold. The compressor outlet should face the intake manifold.
Insert one end of the exhaust tubing into the hole in the mounting flange and the other end to the exhaust manifold's outlet. Weld both ends of the tubing to the flange and outlet.
Join the turbocharger's compressor outlet to the intake manifold with the exhaust pipe purchased to the compressor outlet's size. Use the silicone connectors to secure the pipe.
Affix the turbo oil feed line to the high-pressure oil fitting on the car's engine. Join the other end of the line to turbocharger's oil-in line.
Connect the turbocharger's oil drain line to the oil pan on the car's engine.
Adjust the engine's fuel curve to the specifications of the turbocharger. In some cases, you will need a mechanical fuel enrichment system to control the engine.
